Mbed OS - UDP ping-pong with node.js

Looking for TCP? See mbed-tcp-ping-pong.

Tested on ODIN-W2 EVK, but should work on every Mbed OS 5 device that implements the Network Sockets API.

Get both devices on the same WiFi network, or host the server on a publicly available hostname.

Setting up the server

1. Install a recent version of node.js.

2. Open a terminal.

3. Navigate to the server-in-node directory.

4. Run:

   $ node server.js
   

5. Note down the IP address of the WiFi interface.

Setting up the client

1. Open mbed_app.json and set your connectivity method and WiFi credentials.
2. Open main.cpp and set the IP (or hostname) of the server.
3. Compile and flash on the device.

What it does

The Mbed device will set up a UDP socket to the server, and will send 'ping' the server. The server will respond with 'pong'.
